SPECIFICATION formingpart of Letters Patent No. 708,422, dated September2, 1902.

Application filed January 20, 1902. Serial No. 90,560. (No specimens.)

To (l/ZZ whom it may concern..-

Be it known that I, JACOB STEPHAN, a citizen of the United States ofAmerica, residing at Cleveland, in the county of Ouyahoga and State ofOhio, have invented a certain new and useful Composition Suitable forUse in Making Toy Building-Blocks or the Like; and I hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

This invention relates to a composition suitable for use in making toybuilding-blocks and the like. I

The object of this invention is to provide a composition for makingarticles of the character indicated which are durable and inexpensive.

The method of making my new composition comprises, first, the provisionof a dry mixture composed of Whiting, plaster-of-paris,and whitish orlight-colored or bright sand or pulverized rock material-such, forinstance, as pulverized limestone, pulverized marble, or silica. Theingredients of the said mixture are preferably in the proportions, bymeasure, of one part of plaster-of-paris, one part of whiting, and threeparts of sand or pulverized rock material. A somewhat inferior mixtureis obtained by omitting the plaster-of-paris and substituting Whitingand sand or pulverized rock material. A small quantity of black or darksand or pulverized rock material is added to and thoroughly mixed withthe aforesaid plaster-of-paris, whiting, and whitish or bright sand orpulverized rock material.

Silica sand is preferably used in making the mixture hereinbeforedescribed.

The method already partially disclosed comprises also the preparation ofa liquid compound consisting of white lead,zinc-white, vegetable oil,and paint-drier in the proportions of seven per cent. paint-drier, oneand one-half per cent. white lead, one and onehalf per cent. zinc-white,and ninety per cent. oil. Linseed-oil is preferred. The paintdrierconsists, preferably, of litharge, benzene, and magnesia, comprisingequal parts of the litharge and magnesia and enough benzene tosufficiently thin the drier. The said liquid compound constitutes abinding liquid suitable for use in binding together or effecting anattachment between the ingredients of the dry mixture hereinbeforedescribed, and the said dry mixture and the binding liquid are stirredand mixed together in any approved manner until a plastic mass isformed, and the preferred proportions of the binding liquid and the drymixture for the said mass are preferably ten per cent. of the bindingliquid, by measure, to ninety per cent. of the dry mixture. Theresulting mass is then molded under considerable pressure into toybuilding-blocks and the like.

I would call especial attention to the importance of including black ordark sand or rock material as an ingredient of the dry mixture, becausethe said ingredient when thoroughly mixed with the mass, as it is bymaking it an element of the dry mixture hereinbefore described, makesthe resulting composition a fair imitation of granite.

What I claim is 1. A composition consisting of a dry mixture comprising,as ingredients, Whiting and a whitish or light-colored or bright sand orpulverized rock material, approximately in the proportions specified,and a small quantity of dark sand or pulverized rock material, and abinding liquid mixed with the dry mixture in the proportions required torender the resulting mass plastic and bind and hold the ingredients ofthe dry mixture together.

2. A composition comprising a dry mixture composed of a whitish orlight-colored or bright sand or pulverized rockmaterial,plaster-of-paris, whiting and dark sand or pulverized rockmaterial in about the proportions, by measure, of one part of Whiting,one part of plaster-of-paris, and three parts of the whitish or brightsand, with the dark sand equal in quantity to about one per cent. of thedry mixture, and a binding liquid mixed with the dry mixtureapproximately in the proportions specified.

3. A composition consisting of a dry mixture composed of Whiting andsand or pulverized rock material, approximately in the proportionsspecified, and a binding liquid mixed with the dry mixture andcomprising, as ingredients, white lead, zinc-white, vegetable oil, andpaint-drier.

4. A composition consisting of a dry mixture comprising whiting and sandor pulverized rook material, approximately in the proportionsspecified,and a binding liquid mixed with the dry mixture andcomprising, as ingredients, white lead, zinc-white, linseed-oil, andpaint-drier, approximately in the proportions specified.

5. A composition consisting of a dry mixture comprising sand orpulverized rock material and whiting, approximately in the proportionsspecified, and a binding liquid mixed with the dry mixture in theproportions of about ten per cent. of the liquid and ninety per cent. ofthe dry mixture, with the liquid comprising, as ingredients, White lead,zincwhite, vegetable oil, and paint-drier.

6. A composition composed of a dry mixture and a binding liquid mixedwith the mixture and binding or holding the ingredients of the drymixture together, with the dry mixture comprising, as ingredients, sandor pulverized rock material, plaster-of-paris and whiting approximatelyin the proportions specified, and with the binding liquid comprising, asingredients,white lead zinc-white, vegetable oil and paint-drierapproximately in the proportions specified.

7. A composition comprising a dry mixture and a binding liquid mixedwith the dry mixture approximately in the proportions specified, withthe dry mixture comprising, as ingredients a whitish or light-colored orbright sand or pulverized rock material, plaster-ofparis, whiting, anddark sand or pulverized rock material approximately in the proportionsspecified, and with a binding liquid comprising, as in gredients,whitelead,zinc-white, vegetable oil, and paint-drier in approximately theproportions specified.

In testimony whereof I sign the foregoing specification,in the presenceof two witnesses, this 16th day of January, 1902, at Cleveland, Ohio.

JACOB STEPHAN.
